However,
(1) The apparatus is complicated and expensive.
(2) Although the finger can be bent, it cannot be extended or partially extended, but the entire finger cannot be extended.
(3) Furthermore, since the device unit is equipped with a plurality of motors, for example, it becomes thicker than the therapist's finger and the device unit hits the other fingers, so that bending and extension cannot be performed quickly and alternately. .
An object of this invention is to provide the finger function recovery training apparatus for solving the above problems.

In order to solve the above-mentioned problems, the first invention is a device for performing finger function recovery training by bending and extending a finger of a hand on the affected side of a person. A fixing means for fixing the affected hand, a bending / extending unit arranged in an elongated shape along the direction of the finger of the spread hand of the affected side, and constituting the bending / extending unit A first bar located between the fingertip of the extended finger and the first joint and in contact with the outside of the finger; a second bar located between the first joint and the second joint and in contact with the outside of the finger; A third bar located between the first bar and the second bar and in contact with the inside of the finger, a rotating body provided with all of these bars, and an intermediate between all the bars for rotating the rotating body Rotation shaft located at, and support this rotation shaft at the tip An extension body extending long in the direction of the tip of the finger, a motor provided at the base end of the extension body for rotating the rotating body in the forward and reverse directions, and the bending unit of the bending and extending unit configured as described above An operation unit for operating a motor.
According to a second aspect of the present invention, in the finger function recovery training apparatus, the motor has a torque that stops due to a resistance generated when the finger is fully extended.
The third invention is the finger function recovery training apparatus, wherein a plurality of the bending / extension units are provided according to the plurality of fingers of the affected hand.
According to a fourth aspect of the present invention, the operation unit further includes a plurality of switches for operating the plurality of motors constituting the plurality of bending / stretching units, so that the switch can be operated only by a hand on the healthy side. When the hand on the healthy side is naturally closed, the finger on the affected side which is arranged at a position corresponding to the fingertip on the healthy side and is bent and extended by the motor corresponds to the finger on the healthy side performing the operation. It is a finger function recovery training device characterized by being arranged.
The fifth aspect of the present invention is the finger function recovery training device further characterized in that the bending / stretching unit is provided on the device base with the number of fingers corresponding to the number of the fingers.
According to a sixth aspect of the present invention, the extended body further includes a slide mechanism having the extended body at a tip and sliding the extended body in the length direction of the finger according to the length of the finger. It is a finger function recovery training device.

  According to the first, second, third, fourth, fifth, or sixth inventions described above, the person who undergoes recovery training fixes the affected hand upward by the fixing means provided on the apparatus base. . Then, the finger is bent and stretched by each bending and stretching unit. That is, a finger is inserted between the three bars. At that time, the first bar is located between the fingertip of the extended finger and the first joint, and comes into contact with the outside of the finger. The second bar is located between the first joint and the second joint and is in contact with the outside of the finger. The third bar is located between the first bar and the second bar, and comes into contact with the inside of the finger. Thus, the finger is supported between the three bars.

  Next, the person who undergoes recovery training, that is, the patient, operates the operation unit with the hand on the healthy side, so that the rotating body rotates forward or backward around the rotation axis. The rotation takes place around a rotation axis located in the middle of all the bars. This forward or reverse rotation causes the finger to bend or extend while being supported between the three bars.

As described above, the following effects are obtained.
(1) The affected hand is fixed upward, and the finger is inserted and supported between the three bars near the first joint and the second joint. That is, the first bar is located between the fingertip of the extended finger and the first joint, and comes into contact with the outside of the finger. The second bar is located between the first joint and the second joint and is in contact with the outside of the finger. The third bar is located between the first bar and the second bar, and comes into contact with the inside of the finger.

  Due to the support of this special state, the finger originally has a plurality of joints and has a high degree of freedom, but the degree of freedom is lost, and the finger is sufficiently controlled by the rotation of the three bars around the rotation axis. The Therefore, there is no need to use a plurality of sensors and a plurality of motors as in the prior art device, and only one motor is required for each bending / stretching unit. Therefore, the device can be simple and inexpensive.

(2) Also, with the support of the special state of the finger as in (1) above, not only the finger can be bent, but the entire finger can be extended. That is, since the finger is connected from the fingertip to the first joint (end node), from the first joint to the second joint (middle node), to the second joint and the base of the finger (base node), the end node is bent and extended. For example, the entire finger bends and extends.

(3) According to the second, third, fourth, fifth, or sixth invention, the motor is further stopped by the resistance generated when the finger is fully extended. Further, since the resistance generated when the finger is fully bent is generally larger than that when the finger is extended, the motor naturally stops even when the finger is bent completely.
Therefore, a plurality of motors are not required as in the prior art, and only one motor provided at the base end of the extended body is required, and the size can be reduced accordingly. As a result, the bending and stretching units do not hit other fingers, and bending and extension can be performed quickly and alternately.

(4) According to the third, fourth, fifth, or sixth invention, a plurality of bending / stretching units are provided according to a plurality of fingers of the affected hand. Therefore, a plurality of finger function recovery exercises can be performed simultaneously.
(5) According to the fourth, fifth, or sixth invention, the following effects can be obtained by devising the arrangement of the plurality of switches. That is, the plurality of switches for individually operating the motors are arranged at positions corresponding to the respective fingertips of the healthy side when the healthy side hand is naturally closed, and are also bent and extended by the motor. Since the finger and the finger on the healthy side correspond to each other and the switch is arranged, the person who receives recovery training can operate the device with only the hand on the healthy side. The operation can be performed while the movement of the finger on the affected side is made to correspond.

(6) According to the fifth or sixth invention, the bending / stretching unit is further provided on the radial strip by the number of fingers. Therefore, it is unlikely that the bending / extending unit hits other fingers, and bending and extension can be performed quickly and alternately.
(7) According to the sixth invention, the extension body having three bars and a rotating body at the tip further has the extension body at the tip, and the length of the finger according to the length of the finger. Since it is equipped with a slide mechanism that slides in the direction, it can accommodate the length of the finger of a person undergoing recovery training.

(A) is a whole perspective view which shows the apparatus concerning one Embodiment of this invention, (B) is an enlarged view which expands the principal part of (A). It is a whole perspective view which shows the state which is operating the apparatus of FIG. It is a perspective view which shows the operation part of FIG.

[bar]
The first bar 17, the second bar 21, and the third bar 23 all have a short cylindrical shape. The distance between these three bars B can be adjusted. By this adjustment, the finger 9 inserted between these three bars B (17, 21, 23) is supported in an appropriate state that is neither tight nor loose.

[Rotating body 25]
As shown in FIGS. 4 and 5, the rotating body 25 has a disk shape, and three bars B are arranged at equal intervals in the circumferential direction. Further, as shown in FIG. 6, an adjustment mechanism 51 that adjusts the interval between the bars B is provided. That is, it has two long holes 53 provided in the rotating body 25. And two of the three bars B are provided with a screw 55 inserted into the long hole 53 from the opposite side of the rotating body 25 at the base end and can move along the long hole 53. It is fixed by closing the screw 55 at the moving position.

[Rotating shaft 27]
The rotating shaft 27 is provided at the center of the rotating body 25 and is rotatably supported at the tip of the extending body 29.
[Extended body 29]
The extending body 29 is in the shape of an elongated plate, and the corners are chamfered and rounded. A long slot 57 is formed in the base in the width direction and forms a part of the slide mechanism 37.

[Slide mechanism 37]
The slide mechanism 37 has an elongated plate-like main body 59 that is disposed rearward in the longitudinal direction of the extension body 29. The extension body 29 is fixed to the main body 59 by screws 56 inserted into two places in the longitudinal direction of the long groove hole 57 of the extension body 29. If these screws 56 are loosened, the extended body 29 slides with respect to the main body 59 while the screws 56 move in the long slot 57. The slide is expanded and contracted, and the position of the rotating body 25 provided at the tip of the extending body 29 can be adjusted in the longitudinal direction of the extending body 29.
A base end of the main body 59 is rotatably attached to the apparatus base 3 by a screw 58.

[Motor 35]
A normal motor 35 can be used. A belt 35b is provided on a rotation shaft 35a of the motor via a pulley (not shown) and is wound around a pulley (not shown) provided on the rotation shaft 27 of the rotating body 25 to transmit a driving force.
[Switch 39]
As shown in FIG. 3, the switch 39 is a button type. When the hand 43 on the healthy side is naturally closed, five button switches are arranged at positions corresponding to the fingertips on the healthy side. That is, the switch 39a for controlling the motor 35 for bending and extending the affected thumb is disposed at the position of the healthy thumb. Similarly, a switch 39b for controlling the motor 35 for bending and extending the affected index finger is arranged at the position of the index finger on the healthy side. Similarly, a switch 39c for controlling the motor 35 for bending and extending the affected middle finger is disposed at the position of the middle finger on the healthy side. Similarly, a switch 39d for controlling the motor 35 for bending and extending the affected ring finger is disposed at the position of the ring finger on the healthy side. Similarly, a switch 39e for controlling the motor 35 for bending and extending the affected little finger is disposed at the position of the little finger on the healthy side.

  The healthy side is the left side of the body in this embodiment, but in the case of other patients, it may be the right side of the body. In this case, the thumb of the affected side is used so that the device 1 can be used. A sixth switch 39f is also provided on the side opposite to the switch 39a that controls the motor 35 for bending and stretching the wire. This sixth switch 39f is operated with the thumb on the right side of the body on the healthy side, and bends and stretches the thumb on the left side of the body on the affected side (the little finger of the affected hand 7 in FIGS. 1 and 2). 35 is controlled.

These six switches 39 are provided symmetrically.
A slide lever 61 for adjusting the motor strength is provided at the center in the left-right direction, whereby the motor 35 adjusts the magnitude of the torque that stops due to resistance. The torque of the motor 35 that naturally stops where it bends or stretches is about 0.3 [Nm], which is the torque applied by the skilled therapist to the finger joints, at the level of the force that a person bends in both flexion and extension. .
Actually, the torque that stops due to the resistance generated when the finger is fully extended has a certain allowable range, and the adjustment is set within this allowable range, that is, around 0.3 [Nm].

[Operation unit 41]
The operation unit 41 includes six button switches 39 and a slide lever 61, and a motor control cable 63 is connected to the control box 65. The control box 65 contains a control device that adjusts the magnitude of torque at which each motor 35 stops due to resistance. A control cable 66 for controlling each motor 35 is provided from the control box 65. A power cable 67 is connected to the control box 65 from a power source.

[Action]
The operation of the device 1 according to this embodiment will be described with reference to the flowchart of FIG.
A person who undergoes recovery training operates the operation unit 41 with the hand 43 on the healthy side. That is, the switch 39 disposed at a position corresponding to each fingertip on the healthy side is operated by an action of naturally closing the hand 43 on the healthy side. Initially, the motor 35 is in a state of no power (S1 in FIG. 7), the affected hand 7 is fixed upward, and each finger 9 is prepared to bend and stretch by each bending unit 11 (S2 in FIG. 7).

  When the device power supply (not shown) is turned on, the motor 35 reverses the initial position (S3 in FIG. 7). When this initial position is reached, a person who undergoes recovery training sets each finger 9 to each bending / extending unit 11 and prepares to bend and extend. That is, the finger 9 is inserted between the three bars B. At that time, the first bar 17 is located between the fingertip 13 of the extended finger 9 and the first joint 15 and is in contact with the outside of the finger 9. The second bar 21 is located between the first joint 15 and the second joint 19 and is in contact with the outside of the finger 9. The third bar 23 is located between the first bar 17 and the second bar 21 and contacts from the inside of the finger 9. Thereby, the finger 9 is supported between the three bars B.

  Next, the operation unit 41 is held with the hand on the healthy side. Then, with the middle finger on the healthy side, the switch 39 for controlling the motor 35 for bending and extending the middle finger on the affected side is pressed (S4 in FIG. 7). Then, the motor 35 for bending and extending the middle finger of the affected side rotates normally, and the middle finger of the affected side is bent (S5 in FIG. 7). Similarly, the switch 39 for controlling the motor 35 for bending and extending the index finger on the affected side is pushed with the index finger on the healthy side (S6 in FIG. 7). Then, the motor 35 for bending and extending the index finger on the affected side rotates forward, and the index finger on the affected side is bent (S7 in FIG. 7). Similarly, the other finger 9 is bent by pressing the switch 39. ....

  Then, finally, with respect to the bent finger 9, the switch 39 that has been pressed with the finger 9 on the healthy side is released. Then, the motor 35 for bending and extending the affected finger 9 is reversed, and the affected finger is extended. Similarly, the pressed switch 39 is released with the index finger on the healthy side (n + 7 in FIG. 7). Then, the motor 35 for bending and extending the index finger on the affected side reverses and the index finger on the affected side extends (Sn + 8 in FIG. 7). Similarly, with the middle finger of the healthy side, the pressed switch 39 is released (n + 9 in FIG. 7). Then, the motor 35 for bending and extending the middle finger of the affected side reverses and the affected middle finger extends (n + 10 in FIG. 7).

In this way, it is possible to repeatedly perform bending and extension in the turn-back order for all the fingers 9 in order.
By this operation, the rotating body 25 rotates forward or backward around the rotation axis. The rotation is performed around the rotation shaft 27 located in the middle of all the bars B. By this forward rotation or reverse rotation, the finger 9 is appropriately bent or extended while being supported between the three bars B.
The torque of the motor 35 is such that the motor 35 stops due to the resistance generated when the finger 9 is fully extended (FIG. 5), and therefore the motor 35 naturally stops when the finger 9 is fully extended. Since the resistance generated when the finger 9 is fully bent (FIG. 4) is generally larger than when the finger 9 is extended, the motor 35 also naturally stops when the finger 9 is fully bent.

"Effect of the embodiment"
As described above, according to the device 1 of this embodiment, the following effects are obtained.
(1) The affected hand 7 is fixed upward as shown in FIG. 1, and the finger 9 is located between the three bars B near the first joint 15 and the second joint 19 as shown in FIG. Inserted and supported. That is, the first bar 17 is located between the fingertip 13 of the extended finger 9 and the first joint 15 and is in contact with the outside of the finger 9. The second bar 21 is located between the first joint 15 and the second joint 19 and is in contact with the outside of the finger 9. The third bar 23 is located between the first bar 17 and the second bar 21 and contacts from the inside of the finger 9.

  Due to the support of this special state, the finger 9 originally has a plurality of joints and has a high degree of freedom, but the degree of freedom is lost. That is, when the finger 9 is bent and extended to the end, the position of the finger 9 can take only a specific fixed position, that is, there is no degree of freedom. Since the degree of freedom of the finger 9 is eliminated, it is sufficiently controlled by the rotation of the three bars B around the rotation axis. Therefore, it is not necessary to use a plurality of sensors and use a plurality of motors as in the prior art apparatus, and only one motor 35 is required for each bending / stretching unit. Therefore, the apparatus 1 can be simple and inexpensive.

Also, unlike the prior art, a servo motor or the like that determines the exact position of the device 1 in contact with the finger 9 is unnecessary, and a general motor 35 is sufficient. In addition, since the motor 35 is simply driven by a button, the control can be performed with a simple microcomputer.
The finger 9 is inserted and supported between the three bars B. However, if the fingers 9 are supported by only the two bars B, a load is applied only to the last node, or only the last node is bent or extended. There is a possibility that. In addition, problems such as the base node being bent in the bending direction and the terminal node being bent in the extending direction occur.

On the other hand, the device 1 of this embodiment can bend and extend the finger 9 firmly and can quickly switch between bending and extension.
(2) Further, the support of the special state of the finger 9 as described in (1) above allows the finger 9 not only to be bent but also to extend the entire finger (FIGS. 1 and 5). That is, since the finger 9 is connected from the fingertip 13 to the first joint (end node), from the first joint to the second joint (middle node), to the base of the second joint and the finger 9 (base node), the end node is bent. When extended, the entire finger bends and extends.

Although the thumb does not have a middle joint, it is connected from the fingertip 13 to the first joint (end joint), and from the first joint to the base of the finger 9 (base joint). Bends and stretches.
In other words, two of the three bars B can sandwich the finger 9, and the other can extend the entire finger during extension.
Therefore, regardless of the angle of bending or extension, only the terminal node is bent and bent until the end with the degree of force that the human bends, that is, the torque that stops the motor 35 due to the resistance generated when the finger 9 is fully extended. Next, you only need to extend until the extension is completed. That is, as in the prior art, it is not necessary to finely control the bending of the last clause, how many times the middle clause, and how many times the base clause is bent.

(3) Furthermore, as shown in FIG. 1 and FIG. 2, the bending / stretching unit 11 is provided on the radial strip by the number of fingers 9. In addition, it is only necessary to provide one motor 35 provided at the base end 33 of the extending body 29, and the thickness can be reduced accordingly. As a result, the bending / extending unit 11 does not hit the other fingers 9, and the bending and extension can be performed quickly and alternately.

(4) As shown in FIGS. 1, 2, and 3, the plurality of switches 39 that individually operate the motor 35 correspond to each fingertip on the healthy side when the hand 43 on the healthy side is naturally closed. A person who is placed at the position and receives a recovery training because the affected finger 9 that is bent and extended by the motor 35 corresponds to the healthy finger that performs the operation and the switch 39 is arranged. The device 1 can be operated only with the hand 43 on the healthy side, and the operation of the finger of the hand 43 on the healthy side and the movement of the finger 9 on the affected hand 7 can be made to correspond to each other. .
Further, the device 1 can be produced at low cost by a simple structure in which the button is pushed with the finger on the healthy side and the motor 35 on the affected side is thereby driven.

(5) The extending body 29 having the three bars B and the rotating body 25 at the tip includes a slide mechanism 37 that slides in the length direction of the finger 9 in accordance with the length of the finger 9. It can correspond to the length of the finger 9 of the person receiving training.

"Other embodiments"
In the above embodiment, the slide mechanism 37 slides by the screw 56 that fixes the extension body 29 to the main body 59 of the slide mechanism 37 moving the long slot 57 of the extension body 29. However, in other embodiments, other slide mechanisms can be employed. For example, as shown in FIG. 8, the extension body 71 has two cylindrical shapes, and a columnar main body 73 inserted into the cylindrical shape slides inside the cylindrical extension body 71. It is also possible to perform expansion and contraction.
In the above embodiment, the affected hand 7 is fixed upward, but in other embodiments, the hand may be fixed horizontally or the hand may be fixed downward. Depending on the patient's physical condition, the patient may be less burdensome when facing sideways or facing downward. Even when the postures of these hands are different, the relationship between the finger to bend and stretch and each bar is the same. That is, the first bar is located between the fingertip and the first joint and is in contact with the outside of the finger. The second bar is located between the first joint and the second joint and contacts from the outside of the finger. The third bar is located between the first bar and the second bar and contacts from the inside of the finger.
Therefore, the posture of the entire apparatus is also set differently. That is, when the hand is fixed upward, when the hand is fixed sideways, or when the hand is fixed downward, the posture of each hand is different by 90 degrees, but the posture of the entire apparatus is also different by 90 degrees. Is set.
